Solid electrolytes based on complexes of poly(ethylene oxide) with lithium salts seem to be very promising materials for use in high energy density lithium batteries.1–3 Such electrolytes may also have the important attribute of mechanical flexibility which greatly facilitates the design of an all-solid state battery and, on the other hand, allows the electrolyte to accommodate for the volume change of the cathode during the charge-discharge cycles of the battery. Since it was revealed that ionic conduction takes place principally in the amorphous phase,4 several studies have focused on the synthesis of amorphous solid electrolytes; in most cases the solution has been sought with regard to the solvent by means of cross-linking5,6 or by addition of small-molecule plasticizers,7 but few studies have been directed towards the salts.
